The original grant (#3100AO-118419) included 4 projects that focused on how the human brain combines information from the different senses (i.e. multisensory interactions). These projects (as well as the work of numerous other groups) support a fundamental paradigm shift in the manner in which brain is conceived to be organized. There is now a critical mass of evidence to support a model wherein information from the different senses interactions both during the initial stages of sensory processing and also within primary cortical regions (and potentially even subcortically). What's more these interactions directly impact perception and performance.
The projects of the current grant will continue to focus on multisensory interactions via a series of synergistic projects.
